Objective To evaluate the effect of virtual reality(VR)on cognitive function and quality of life in patients with Parkin-son's disease. Methods A systematic search of CBM,CNKI,Wanfang data,VIP,Cochrane Library,Web of Science,Embase,and PubMed was carried out to identify randomized control trials(RCT)about the effect of VR technology on pa-tients with Parkinson's disease from inception to February 29th,2024.The control group received routine cogni-tive training,balance training or physical therapy,and the experimental group received VR technology.The quali-ty of articles was evaluated using the Cochrane Collaboration's 5.1.0 RCT risk assessment tool for bias.The meta-analysis was performed using Revman5.4.GRADE was used to evaluate the evidence quality of outcome indica-tors. Results A total of 13 literatures involving 426 patients were included.Allocation concealment and blind methods were not described in most literatures,and selective reporting of research results or other biases was unclear.VR tech-nology could improve the Motreal Cognitive Assessment(MoCA)score(MD=1.11,95%CI 0.31 to 1.90,P=0.006),Trail Making Test(TMT)-A score(MD=-6.25,95%CI-11.71 to-0.78,P=0.030)and depression scale score(SMD=-0.56,95%CI-0.95 to 0.18,P=0.004)of patients with Parkinson's disease;however,it did not improve TMT-B score(MD=-6.01,95%CI-28.16 to 16.14,P=0.590),Unified Parkinson's Disease Rat-ing Scale(UPDRS)-Part II score(MD=-2.11,95%CI-4.97 to 0.75,P=0.150)and Parkinson's Disease Ques-tionnaire(PDQ-39)score(MD=-0.92,95%CI-4.03 to 2.19,P=0.560).For quality of evidence,MoCA score,UPDRS-Part II score and PDQ-39 score were low,and depression score and TMT score were moderate. Conclusion VR technology can improve the cognitive function and depression of patients with Parkinson's disease;how-ever,no significant improvement is found in activities of daily living and quality of life.

Objective:To determine the status of nutritional literacy and its influencing factors among the peritoneal dialysis (PD) patients. Methods:The patients who underwent PD and long-term follow-up in the Department of Nephrology,General Hospital of Eastern Theater Command between January and October,2023 were enrolled in this study. The status of nutritional literacy in the patients was assessed through collecting and analyzing the data on the patients' general information,the current nutritional status,and laboratory-and dialysis-related indicators. Results:The average score of nutritional literacy in the enrolled patients were (24.49±3.35). Significant differences in nutritional literacy scoring were observed in the different patient subgroups according to the patients' educational background,dialysis time or times of receiving multidisciplinary diet guidance (all P values<0.05). The nutritional literacy levels of PD patients were negatively correlated to the concentrations of serum calcium and prealbumin,and left ventricular posterior wall thickness,and postively correlated to prealbumin level(P<0.05). Basing on multiple linear regression analysis,the times of receiving multidisciplinary diet guidance,educational background and serum prealbumin level were identified as independent influencing factors for the nutritional literacy levels in PD patients,respectively (all P values<0.05). Conclusions:The present study showed that the nutritional literacy of PD patients was in the middle level. In clinical practice,to enhance multidisciplinary diet guidance and management at the early stage of PD could contribute to improve the nutritional status of PD patients. In addition,to increase the patients' nutritional knowledge and health management ability might be also helpful for the nutritional levels of PD patients.

BACKGROUND: Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP). OBJECTIVE: This study identified the effects of CMFST on the incidence of LBP in military recruits. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training. MAIN OUTCOME MEASURES: At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ). RESULTS: A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05). CONCLUSION This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

Objective: To explore the effect of moxibustion at Shenque (CV 8) on myocardial structure and function in exercise-induced fatigue rats. Methods: A 12-week treadmill running training was performed to create an exercise-induced fatigue rat model. Sixty eligible male specific-pathogen-free grade Sprague-Dawley rats were randomly divided into a blank group, a control group, a model group, a non-meridian non-acupoint group, a Zusanli (ST 36) group and a Shenque (CV 8) group, with 10 rats in each group. Rats in the blank group did not receive treadmill running training or moxibustion. Rats in the control group did not receive treadmill running training but received mild moxibustion at Shenque (CV 8). Rats in the model group received treadmill running training but no moxibustion. Rats in the non-meridian non-acupoint group, the Zusanli (ST 36) group and the Shenque (CV 8) group received moxibustion at the non-meridian non-acupoint points, Zusanli (ST 36) or Shenque (CV 8) immediately after each treadmill running training, 15 min each time, once a day for 5 consecutive days a week at a 2-day interval, 60 times of moxibustion in total. Left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVESd), left ventricular diastolic volume (LVDv), left ventricular systolic volume (LVSv), ejection fraction (EF), stroke volume (SV), early diastolic peak flow velocity of mitral valve (E) and late diastolic peak flow velocity of mitral valve (A) of each group before and after the last treadmill running training were measured. Blood was collected 6 h after the last treadmill running training, and serum C-reactive protein (CRP), myoglobin (Mb), creatine kinase-myocardial band (CK-MB), cardiac troponin I (cTnI) and cardiac troponin T (cTnT) levels were detected. Finally, the heart was separated, the heart mass (HM) was measured, the cTnT level of the myocardial tissue was detected, the ultrastructural changes of the left ventricular myocardium were observed by transmission electron microscope, the left ventricular fraction shortening (LVFS), E/A and heart mass index (HMI) were calculated. Results: Compared with the same group before treatment, the rat cardiac LVEDd, LVESd, LVDv, LVSv, SV, E and A were significantly increased (all P<0.01), and the rat LVFS, E/A and EF were significantly decreased (all P<0.01) in the model group and the non-meridian non-acupoint group after treatment; the rat cardiac SV, LVDv, LVSv, E and A were all increased (all P<0.01), while E/A and EF were decreased (all P<0.01) in the Zusanli (ST 36) group after treatment; the rat cardiac LVDv, E and A were significantly increased (P<0.01 or P<0.05), and E/A was significantly decreased (P<0.01) in the Shenque (CV 8) group after treatment. After treatment, compared with the blank group, the rat cardiac LVEDd, LVESd, SV, LVDv, LVSv, E, A, the serum CRP, Mb, CK-MB, cTnI, cTnT and HMI, and the myocardial cTnT were increased (all P<0.01), and the LVFS, E/A and EF were all reduced (all P<0.01) in the model group; compared with the model group and the non-meridian non-acupoint group, rats in the Zusanli (ST 36) group and the Shenque (CV 8) group showed decreased LVEDd, LVESd, SV, LVDv, LVSv, E, A, serum CRP, Mb, CK-MB, cTnI, cTnT and HMI, and myocardial cTnT (P<0.01 or P<0.05), along with increased LVFS, E/A and EF (all P<0.01); compared with the Zusanli (ST 36) group, Mb and A of the Shenque (CV 8) group were decreased (both P<0.01), while both E/A and EF were increased (P<0.01, P<0.05). Transmission electron microscopy examination showed that myofibrils in the blank group and the control group were neatly arranged with clear light and dark bands; the model group and the non-meridian non-acupoint group showed different degrees of myofibril disintegration and breakage, increased and aggregated mitochondria of different sizes, and increased electron density. The myofibrils in the Shenque (CV 8) group and Zusanli (ST 36) group were arranged neatly with clear light and dark bands, and compensatory hyperplasia of mitochondria. Conclusion: Moxibustion at Shenque (CV 8) and Zusanli (ST 36) both can effectively improve the occurrence of myocardial remodeling in exercise-induced fatigue rats, and the effect of moxibustion at Shenque (CV 8) is better in improving cardiac function.

Objective To evaluate the clinical effect of electromagnetic navigation system to locate the distal locking screw of tibia intramedullary nail. Methods From February 2010 to December 2016, 79 cases of tibia shaft fractures requiring treatment with intramedullary nailing were selected and divided into the navigation group and free hand locking group according to intramedullary nail locking methods. Forty-four cases in navigation group used an electromagnetic navigation system to lock the distal end of the intramedullary nail,while 35 cases in free hand locking group used a free-hand technique. The intraoperative X-ray exposure time,distal locking time,healing time, and the success rate of one-time distal locking were recorded compared between two groups. Results The average time of diatal locking using electromagnetic navigation technology was less than that of the free hand locking group,and the exposure time of fluoroscopy was also reduced, the differences were significant(P ＜ 0. 05). There was no difference in fracture healing time between the two groups(P ＞ 0. 05), one-time success rate of navigation group was 100％,which was higher than 37. 34％ of the free hand locking group, the difference was significant(P ＜ 0. 05). Conclusion Compared with free hand technology, the advantage of using electromagnetic navigation system to lock the distal nail of tibia intramedullary nail is high efficiency, short locking time and no radiation.

Objective To explore the effect of corpus luteum blood flow measured by three-dimensional power Doppler ultrasound on pregnancy in elderly women.Methods We selected 464 elderly women with normal ovulation who came to the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to July 2017 as study group.Another 436 women aged less than 35 years old who planned pregnancy in the same period were selected as control group.The clinical data were compared between the two groups.Results There was no significant difference in average diameter of dominant follicles and endometrial thickness at each monitoring point between the two groups (P＞0.05).There was no significant difference in corpus luteum blood flow grade 1 day after ovulation (P＞0.05),but corpus luteum blood flow grade 7 to 9 days after ovulation in study group was significantly reduced as compared with control group (P＜0.05).The two groups did not differ significantly in corpus luteum volume (V)or vascular parameters 1 day after ovulation,corpus luteum V 7-9 days after ovulation (P＞0.05).However,luteum vascularization index (VI),flow index (FI)and vascularization flow index (VFI) significantly decreased in study group compared with control group (P＜0.05).Biochemical pregnancy rate and clinical pregnancy rate were 1 6 .3 8% and 9 .05 % in study group ,which were significantly lower than 2 3 .1 7 % and 19.04% in control group,respectively (P＜0.05).Miscarriage rate of biochemical pregnancy in study group was 7. 33%,significantly higher than 4.13% in control group (P＜0.05).Corpus luteum V and vascular parameters in women with biochemical pregnancy abortion in both groups were significantly lower than those with clinical pregnancy (P＜0.05).Conclusion The decreased of blood supply of the corpus luteum in embryo implantation window of elderly women may be related to the reduction of endometrial receptivity and pregnancy rate.Regardless of old age,biochemical pregnancy abortion is likely to lead to loss of corpus luteum blood supply,which results in pregnancy failure.

Objective Reports are rarely seen on the treatment of blood blister-like aneurysm(BBA)of the internal carotid artery with the overlapping low-profile visualized intraluminal support device(LVIS)stent. This study was to investigate the effects of overlapping versus non-overlapping LVIS stent-assisted coiling in the treatment of BBA. Methods We retrospectively analyzed the clinical data about 15 cases of BBA of the internal carotid artery treated in our hospital from February 2015 to February 2017,11 by o-verlapping and the other 4 by non-overlapping LVIS stent-assisted coiling. Using Raymond-Roy Occlusion Classification(RROC),we evaluated the effects of treatment immediately and at 1 week after operation. We followed up the patients from April 2015 to October 2017 and analyzed the results of follow-up digital subtraction angiogra-phy(DSA)and modified Rankin Scale scores(mRS)of the patients. Results RROC showed 10 cases of grade Ⅰ and 1 case of grade Ⅲocclusion in the overlapping group and 3 cases of gradeⅠand 1 case of gradeⅡin the non-overlapping group right after operation. In com-parison,there were 11 cases of gradeⅠin the overlapping group and 2 cases of grade Ⅰ and 2 cases of grade Ⅱ in the non-overlapping group at 1 week postoperatively.DSA at the end of the follow-up exhibited 9 cases of gradeⅠand 1 case of gradeⅡin the overlapping group and 1 case of grade Ⅰ,2 cases of grade Ⅱ and 1 case of gradeⅢin the non-overlapping group. Satisfactory prognosis was ob-served in all the 15 cases,with mRS=0 in 9 cases and mRS = 1 in 2 cases in the overlapping group and with mRS=0 in 3 cases in mRS=1 in 1 case in the non-overlapping group. Conclusion Overlapping LVIS stent-assisted coiling is safe and effective for treat-ment of BBA of the internal carotid artery.

Objective Intravascular interventional embolization has become the preferred method for the treatment of anterior communicating artery aneurysms.The purpose of this paper was to study the guiding significance of dual vessel fusion technique for in -terventional surgery of complex anterior communicating artery aneurysms. Methods A retrospective analysis was conducted on the clinical data of 31 patients with complicated anterior communicating artery aneurysms in our department from March 2015 to June 2016. All patients underwent two-vessel fusion, DSA angiography, and three-dimensional reconstruction of unilateral internal carotid artery and the images were compared to identify whether the aneurysm met the true size,the exact convergence point of bilateral A 1 and ante-rior communicating artery, anterior communicating artery aneurysm and anterior communicating artery and so on. Results There were 31 cases identified by dual vessel fusion technique on the consistency of aneurysms to true volume and 28 cases by three-dimensional reconstruction of unilateral internal carotid artery.There were 31 cases identified by dual vessel fusion technique on the exact convergence point of bilateral A 1 and anterior communicating artery and 9 cases by DSA angiography.There were 31 cases identified by dual vessel fusion technique on variations of anterior communicating artery complex and 24 cases by DSA angiography.There were 27 pa-tients who attained the optimal DSA machine projection angle by the dual vessel fusion technique which was the same as that of the unilateral internal carotid artery,in addition,the other 4 cases got better optimal DSA machine projection angle than those by three-dimensional reconstruction of unilateral internal carotid artery. Conclusion The dual vessel fusion technique helps surgeons to fully understand the anatomical relationship between anterior communicating artery complex and aneurysm,which has important guiding significance in making surgical strategies for complicated anterior communicating artery aneurysms,selecting embolization work angles and real-time observation during embolization.

Objective: To explore the expressions of transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin 1 (TRPA1) in the dorsal root ganglion (DRG) and their action mechanisms in the rat model of orchialgia. METHODS: The models of orchialgia were established in male SD rats by injection of 2% acetic acid into the testis. Then the number of spontaneous pain responses and withdrawal latency in the model rats were recorded by behavioral tests and the expressions of TRPV1 and TRPA1 in T13－L1 DRGs determined by RT-qPCR, Western blot and immunofluorescence staining. RESULTS: Compared with the normal control rats, the orchialgia models showed a significant increase in the number of spontaneous pain responses (0.13 ± 0.35 vs 22.63 ± 3.42, P<0.01) and a decrease in the withdrawal latency at 4 hours after injection (［12.75 ± 1.50］ vs ［4.85 ± 1.00］ s, P<0.05). The mRNA expressions of both TRPV1 and TRPA1 were observed in the membrane of the neurons in the DRG, the former increased by 1.77 times and the latter by 1.75 times that of the control (P<0.05). CONCLUSIONS The expressions of TRPV1 and TRPA1 were up-regulated in the DRG of the rat models of orchialgia, which may be involved in the allodynia and hyperalgesia of the rats.
